Could be jealousy, spending money on a sports car not something practical, worries of other women taking notice (which they really don't, as evident by lots of places)-- anything. It sure isn't working for me, though, since I'm seeing a bunch of men who made a poor choice of not discussing it with their spouse.

How pissed would one of us be if our wives/sig-others payed ~$25k on a closet overhaul complete with contents? How about a new kitchen with all new counters, appliances, and lighting instead of it going to our car or man-cave? It's the same thing there. If any of those guys had kids, they just blew the plans that they and their wives made for a bigger place, bigger/safer/newer car for them and their family. Marriage isn't buying a puppy, it's coming together as partners.
